维度参数(Parameters)超参数(Hyperparameters) 本质 模型内部学到的知识 控制模型学习的规则 调整方式 通过数据自动优化(如梯度下降) 人工设定或自动调参 例子(线性模型) w, b 学习率、训练轮数 例子(Transformer) Q/K/V矩阵、Embedding矩阵 层数、注意力头数、Dropout比例 七、扩展思考 参数与超参数
1. 参数(parameters)/模型参数 由模型通过学习得到的变量,比如权重 和偏置 2. 超参数(hyperparameters)/算法参数 根据经验进行设定,影响到权重 和偏置 的大小,比如迭代次数、隐藏层的层数、每层神经元的个数、学习速率等
有些概念其实,很纠结,它到底是属于机器学习呢,还是属于深度学习呢?比如说,分类与回归,这个有些是很难界定的,有人说,它属于深度学习,又有人说,它属于机器学习。 其实争论这些,好像并无太大意义,就像一个男生对一个姑娘宠溺的说:这天下,是你的;而你,是我的。 所以,其实不管这个概念属于谁,深度学习是属于机器...
比如算法中的learning rateaa(学习率)、iterations(梯度下降法循环的数量)、LL(隐藏层数目)、n[l]n[l](隐藏层单元数目)、choice of activation function(激活函数的选择)都需要来设置,这些数字实际上控制了最后的参数WW和bb的值,所以它们被称作超参数。 实际上深度学习有很多不同的超参数,之后也会介绍一些其他的...
In this tutorial, we’ll explain the difference between parameters and hyperparameters in machine learning. 2. Parameters In a broad sense, the goal of machine learning (ML) is to learn patterns from raw data. ML models are mathematical formalizations of those patterns. For example, is a fam...
In machine learning, both parameters and hyperparameters are crucial for training a model, but they serve different purposes: Parameters Learned from data: Parameters are the internal variables of a model that are automatically estimated during the training process. ...
